Gunners sign striker Pierre-Emerick Aubameyang from Borussia Dortmund

Arsenal have signed Gabon striker Pierre-Emerick Aubameyang from Borussia Dortmund for a club record ?56m, Arsenal's website has confirmed.

Since the beginning of the 2015-16 season the 28-year-old scored 100 goals for Dortmund – 45 more than any player has scored for Arsenal in the same period.
